Biomass accumulation in natural Nothofagus pumilio stands Fireland-Chile

Forest Systems, 1995
The aim of this study was to analize the biomass accumulations in two Lenga (Nothofagus pumilio) natural forests, growing at 250 meters above sea level in Tierra del Fuego-Magallanes, Chile. Allometric equations were developed, based on destructive sampling (91 trees) in order to estimate the biomass.

Simulated warming does not impair seedling survival and growth of Nothofagus pumilio in the southern Andes

Perspectives in Plant Ecology, Evolution and Systematics, 2013
Abstract It has been predicted that subalpine forests will be negatively affected by global warming; however, direct responses to experimental warming have been scarcely examined in these systems. In this study we evaluated the effects of higher temperatures with and without water addition on the survival and growth of recently emerged (small) and ...

The First Firn Core From the Cordillera Darwin Icefield: Implications for Future Ice Core Research

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract The Southern Hemisphere westerly winds (SHWWs) (45–65°S) are important regulators of the Southern Hemisphere climate. The scarcity of observational records at the core of the wind belt hinders our understanding of the environmental impact and long‐term variability of the westerly winds.

Mortality of the outbreak defoliator Ormiscodes amphimone (Lepidoptera: Saturniidae) caused by natural enemies in northwestern Patagonia, Argentina Mortalidad del defoliador epidémico Ormiscodes amphimone (Lepidoptera: Saturniidae) causada por enemigos naturales en el noroeste de la Patagonia Argentina

Revista Chilena de Historia Natural, 2012
Outbreaks of the defoliator moth Ormiscodes amphimone are occurring more frequently in numerous Nothofagus forests of Patagonia. However, little is known about the life history of this species including its natural enemies as mortality agents.

Tree recruitment at theNothofagus pumilioalpine timberline in Tierra del Fuego, Chile [PDF]

Journal of Ecology, 2000
Summary1 Nothofagus pumilioforms an abrupt alpine timberline (AT) at 690 m a.s.l on Balseiro mountain, 54 °S, Tierra del Fuego, Chile. Fruit and seed rain (quantity and quality), emergence, density and survival of seedlings were studied across an altitudinal gradient (450–740 m) from within the forest to above the AT.2 Fruit rain generally declined ...

Modificación del crecimiento y de la calidad de fustes en un raleo fuerte de un rodal en fase de crecimiento óptimo inicial de Nothofagus pumilio

Ecología Austral, 2001
Nothofagus pumilio (Poepp. et Endl.) Krasser es la especie forestal nativa de mayor importancia en la Patagonia. Existen varios propuestas y ensayos silvícolas para la especie, pero ninguno de ellos se basa en observaciones a largo plazo. El objetivo de

Reconstrucción espacial y temporal de la ocurrencia de avalanchas de nieve en los Andes patagónicos utilizando técnicas dendrocronológicas Dendrochronological reconstruction of spatial and temporal patterns of snow avalanches in the Patagonian Andes

Revista Chilena de Historia Natural, 2009
Las avalanchas de nieve representan un importante riesgo natural en diversas regiones montañosas alrededor del mundo. Daños a infraestructura y pérdidas de vidas humanas son reportados frecuentemente en relación a eventos catastróficos de avalanchas.

Genomic responses to climate: Understanding local adaptation in the Andean tree species Nothofagus pumilio and implications for a changing world

Plants, People, Planet
Societal Impact Statement Forest trees tend to be strongly genetically adapted to their local environments, but climate change will probably subject trees to novel combinations of precipitation, temperature, and photoperiod.

Intraspecific trait variation and covariation in a widespread tree species (Nothofagus pumilio) in southern Chile

New Phytologist, 2010
• The focus of the trait-based approach to study community ecology has mostly been on trait comparisons at the interspecific level. Here we quantified intraspecific variation and covariation of leaf mass per area (LMA) and wood density (WD) in monospecific forests of the widespread tree species Nothofagus pumilio to determine its magnitude and whether ...
